Serial No. 429,996.

' citizen of the United States, and resident of the borough of Brooklyn,city of Yew York, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in 'lype-V'iting Machines,of which the following is a specification.

My invention relates especially to ribbon mechanism for typewritingmachines and its object generally stated 'is to provide improvedmechanism of this class.

More specifically, one object of the. invention is to provide automaticcross feeding devices for a ribbon which is controlled by a centralribbon guide which guides the printing portion of the ribbon crosswiseof the printing line.

Another object is to provide interchangeable automatic cross feeddevices, whereby the extent of cross feed may be varied.

Another object is to provide means for dispensing' with the automatic.cross feeding devices and for enabling the ribbon guide to be set inselected positions whereby the ribhon may he used in predeterminedlields extending lengthwise of the. ribbon.

Another object isto provide nrezzns operative automatically to cut out:or render inoperative the longitudinal ribbon feeding mechanism when thecarriage is released from its letter fee-ling devices. said automaticmeans being operative both by the usual release key of the machine. andalso by one or more titlltlltltlllg keys.

Other objects will hereinafter appear.

To the above ends, my invention consists in the features ofconstruction, combinations of devices and arrangements of partshereinafter described and particularly pointed out. in. the claims.

My invention is especially adapted-to the. Smith Premier typewritingmachine,.which is an under-strike machin and in the pres- -eut instanceI have hun-n the invention a pplied to that machine, but the nature ofthe invention such that various of its features may be applied to otherstyles of writing machines.

Referring first n-" 'e especially to Figs. 1, 2 and 3, the main fame ofthe machine is shown as t'tlllipl'ifilllg a base 1. posts 2 and a topframe part or plate 3. A set of type. bars (not shown) are eirt'rularlyarranged on the top plate and are connected by the usual train ofactuating devices (not shown) with linger keys 4. The type bars, when atuated. coi'iperate with the under side of a platen .7 having an axle awhich is support-2d on the side bars I of a carriage, which carriagefurther comprises a front bar 8 and a rear bar 9. The front and rearbars are oppositely grooved to cooperate with antigrooved front and rearguide rails numbered respectively 11 and 12, said guide rails beandshaft 16. Said shaft at its rear end carries an escapement wheel 19having teeth 20 which are adapted to cooperate with a loose dog 21pivoted on a carrier 22 which in turn is pivoted on a carrier 23carrying the fixed dog 24. The carrier is secured to the upper end of avertical rock shaft 25 journaled on the frame of the machine, the lowerend of said rock shaft carrying an arm 25 which connects with the usualuniversal bar or gate (not shown), said gate being operated when each ofthe printing keys 4 is depressed, so as to cause the escapementdogs 21and 2st to cooperate with the teeth of the escapement wheel to permitthe carriage to be drawn a letter space distance leftward by thecarriage power. Said carriage power comprises a wheel 26 connected by aband or strap 27 with the carriage. Integral with the wheel 26 is ahollow drum 28 which contains the usual power spring, said drum beingloosely mounted on a drivin shaft 29 which extends fore and aft of themachine and is journaled in the left-hand front and rear posts 2. Aribbon spool 30 is loosely n10unt ed on the driving shaft 29 just backof the front co ner post and is held from movement lengthwise of saidshaft but is adapted to be turned in unison therewith by devicescomrising ratchet teeth 31 integral with the rear ange of the spool 30and a sleeve 32 slidably mounted on the shaft 29 and provided withratchet teeth 33 which are adapted to mesh with the ratchet. teeth 31.The driving or ribbon spool shaft 29 is normally connected with thespring drum 28 by devices comprising a ratchet wheel 34 fixed to therear end of the shaft 29 and a pawl 35, said pawl being pivoted betweenits ends to the spring drum 28 at 36. A coiled spring 37 is connected atone end by a screw 38 with one of the s okes of the wheel 26, saidspring at its at er end engaging a pin 39 on one arm of the awl 35 andtending constantly to maintain the tooth 40 on the other arm of saidpawl in en agement with the teeth of the ratchet whee 34 At the oppositeside of the machine a ribbon spool shaft 41 is journaled on therighthand posts 2 and carries adjacent to the rear ost a ribbon spool42,said spool being mounted so that it may turn independently of theshaft 41, but being held from endwise motion therealong. The spool 42 isadapted to be connected to turn in unison with the shaft the rear faceof a sleeve 45, which sleeve may be moved endwise of the shaft 41 but isconnected to turn always in unison there with. A crank arm 46 has a hub46 which is arranged on the rear end of the shaft 41 and is suitablyfixed thereto. The shafts 29 and 41 are connected to turn in unison by arod 47 which is loosely mounted on slctted brackets 48 depending fromthe top plate, said rod 47 terminating in spherical ends -l9, one ofwhich is detaehably seated in a depression in the ratchet wheel 34; andthe other in a depression in the,crank-arm 4G. The usual or suitablereversing mechanism may be employedto move the sleeves 32 and 45alternately into and out of connection with their associate ribbonspools so as to reverse the direction of longitudinal feed of s theribbon. By this alternate turning of the spools the ribbon is fedlongitudinally back and forth across the printing point. Thislongitudinal feed of the ribbon is derived from the connection of thespring drum 28 with the driving shaft 29, said connection com risin theratchet wheel 34 and the paw 35, he pawl being the driver and theratchet wheel the driven part. The nature of the connection is such thatit is operated during the movements of the carriage from right to leftacross the top plate, but when the carriage is returned or restored inthe 01p osite direction the pawl tooth 40 will s ide idly over the teethof the ratchet wheel 34 without affecting said ratchet wheel or thespool shafts. I

The rear flange of the s 001 30 is somewhat nearer the front of t emachine than thefront flange of the spool 42 and the ribbon- 50 isdirected from one of these spools to'the other in an off-set path, beingled upward from the spools through suitable slots in the top plate andthence directed inward toward the middle of the machine where it isturned or folded over oblique turning bars 51 carried on a slidablemember or guide plate52. The ribbon passes from above the spool 30 overthe top plate, under the lefthandportion of the guide 52, up over thefront turning bar 51 toward the rear of the machine, over the typeopening between the two turning bars, over the rear turning bar, thencedown under theright-hand side portion-of the guide 52, over the topplate and down-through the slot therein to the spool 42. The arrangementis such that the printing portion of the ribbon, or that ortionbetweenthe turning bars and overlying the same, extends transvcrselyor at r ghtangles to'the length of the platen and the lines embraces the guide bar54.

portions of the ribbon between the spools. I

The printing point is indieated by the dotted square 53 in Fig. 3. andfrom an inspeetion of this figure it will be seen that the printing,pointlies back of the left-hand rib- )Oll spool and in front of theright-hand ribbon spool and that the types will strike 5 5 onee been setin the position for useby adonly the printing portion of the ribbon.

'The guide plate 52 is mounted to slide on i a fuide bar 54 on the topplate at the rear site of the mat-blue,

the guide plate being I provided with a lip 51', so that. it partiallyThe guide plate E 52 at. its front side cooperates with a seeond 5 guidebar on the top plate, said guide plate. at its front side being confinedbetween the guide bar 55 and the under side of the front rail 11. Theguide bar is provided with lingers. 52 which extend downward through aslot at It will be understood that the guide plate 52 is adapted to bemoved lengthwise of the guide bars to present different widthwise partsof the printing per:

tion of the ribbon to the types. This movement of the guide plate ma ybe accomplished by hand as in the Smith Premier machine or automaticallyas provided for by my present 1 invention.

The parts thus far specifically described are or may be the sam as thecorresponding parts of the No. :2 Smith Premier typewriter. and it istherefore not deemed neeessary to describe them in greater detail. .Theguide plate 52 has a forwardly extending part 52 on which is pivoted at57 an angled member or part 58 provided with afinger p1eee 59 and arem-wardly prtnectmg lug (it). top of the mat-lune frame and a guide bar(31 seem-ed thereto by screws (32. The guide bar .61 is'provided with alug or having a concave fat-e61 which is adapted to 006p- ,erate withthe finger piece. 59 when the guide .is moved leftward to render theribbon numerative. The front end of the part 58 is beveled to provide apointer wlneh to operates with an indicating plate (33.

The ribbon mechanism thus Far described -1nay be employed with a ribbonof uniform ehara'eter throughout, but is espeeially adapted for use witha ribbon divided longitudinally into a plurality of tields or stripes ofdifferent characteristics; sueh. for

and the field 1' to be t'olored with purple.

t'opying'v ink. When a ribbon likethat just describwl has beenheretofore emploved 1n the \o. '2 Smith lrenner marlune, said ribbon hasbeen usually adapted to be written on in a single line lengthwise ot'the field a,

in a single line lengthwise of the field I), and Y in a plurality ofparallel lines or paths lengthwise of the broader field (a lo the easeof the fields I! and I. after they have i so on until the entire widthof the field has been thus used. 3y my present invention I provide forusing a ribbon like 50 in a line or path lengthwise of the field H andin a line or path lengthwise of the field I), the guide 52 being set foreither lield and held in set position by the frirtion between the guideand its guide bars .3 1 and When, however, the broader tield 1' is to beemployed, I provide means for automat'irally reciprocating the uide 5:!from side to side so that the ribbon is fed erosswise bark and forthfrom one edge of the field 1' to the other sinmltaneously with thelongitudinal feed of said ribbon. the result being that the types willfollow a serpentine path extending, lengthwise of the field 1' andenrvin; substantially from one ed' e to the other thereof. 'hen theribbon at) is replaced by a ribbon of uniform eharaeter througl'iout.its width. my invention enables the extent of the automatierta-iproratory movements of the guide 5:2 to be inereased so that theribbon may be fed erosswise to the full ex tent of its width and theserpentine path will wave or eurve substantially from one edge to theother thereof. I

The automatic means for sliding the guide plate 52 to and fro, eomprisesan arm (34 (Figs. 1, It, 4 and 5) pivoted at (35 to the guide plate 52and extending horizontally over the latter toward the right hand side ofthe mat-lune. leat' springtitt, secured to the guide plate by a screw6T,'eoiiperates with the arm (it and tends constantly to press itforward. the forward movement of the arm It} being limited by the hip'30 on the part 55, which in turn is arrested by a lug 52 integral withand extending forward and upward from the glide plate 52. The

right-hand end of the arm Ulis beveled as indieated at (34. and said armis provided near its free end with a slot (38 whieh is adaptedtoengagetheupperend of a vertieallydis- 69 is effected, after which thefinger piece posed operating arm 69. said operating arm, l as shown inFigs. 1 and 4, extending downl ward through an opening in the to plate lnear the right-hand side of the machine and I being pivoted at 70 t0 ,alug 71 extending l inward from the rightshand side of the base l l 1.This operating arm is adapted to be swung. on its ivot inward toward themid dle of the mac inc and in the opposite direction by interchangeabledevices which receive motion from the right-hand ribbon s ool shaft 41.These devices are most c earlyshown in Figs. 5 and 6 and comprise aneccentric carrier 72 which has a hub 73, the latter receiving a setscrew 74 which engages the shaft 41 and secures the eccentric carrier ina fixed relation therewith. At its front side the eccentric carrier hasformed integrally with it an eccentric 75, and at its rear side, asmaller eccentric 76. T119313 eccentrics coiiperate with suitable strapsnumbered respectively 77 and 78. The strap 77 is held in place by aplate 79 which is secured to the carrier 72 by a headed screw 80 and'the strap 78 is similarly held in place by a. plate 81 which is securedto the carrier by screws 82. The. strap 77 is provided with a fingerpiece 83 and diametrically opposite thereto with an extension 84 formedwith a slot 85. The smaller strap 78 is similarly provided with a fingeriece 86 and an extension 87 formed wit a slot 88. The slotted strapextensions 84 and 87 are ada ted to cotiperate one at a time with headedstuds or pins extending oppositely from the front and rear faces of theoperating arm 69 and numbered respectively 89 and 90. In the drawingsthe slot 88 of the extension 87 is shown engaged with its associate stud90, thus rendering the strap 78 and the eccentric 76 operative, saidstrap and said eccentric coiiperating during rotary movements of theshaft 41 to transmit a reciprocatory movement to the operating arm 69and from it through the arm 64 to the carrier 52. The throw of theeccentric 76 is sutiicient to reciprocate the uide 52 to an extent thatwill enable the fielt c of the ribbon to be moved automatically back andforthwidthwise of the printing point so that substantially th full widthof said field ma y-be employed.

If it be desired to dispense with the automatic cross feed and make useof either of the fields a or b, the arm 64 may be moved rearward on itspivot against the spring 66 until the slot 68 disengages from the upperend of the operatin arm 69. This rearward movement of t ie arm 64 may beaccomplished by pressing rearward on the finger piece 59, causing thelug 60 to turn the arm 64 on its pivot against the spring 66 untildisconnection from the operating arm 59 may be used to slide the guideplate 52 downward until the s to the proper position for using eitherthe If it be desired to entirely dispense with the use of the ribbon,the guide plate 52 may be moved leftward by hand until the stem of thefinger piece 59 is seated in the depression 61". This movement of theguide is sufficient to leave the printin point uncovered so thatmimeograph wor may be done or the types may be cleaned, etc.

When it is again desired to connect the guide plate 52 with theoperating arm 69 said guide may be slid either toward the right ortoward the left to cause the slot 68 to ret ngage-the upper end of saidoperating arm. It the slot 68 happens to be at the right-of the upperend of the arm 69 the guide 52 is moved leftward so that the front edgeof the arm 61% will slide along said operating arm until said arm is enaged by the slot owing to the pressure of t e spring 66. If the free endof the arm 64 is at the left of the upper end of the operating arm 69,the guide 52 is slid rightward by hand until the bevel or cam edge 64contacts with the upper end of the arm 69, causing the arm 64= to beforced rearward until the slot 68 engages said operating arm.

If a ribbon of uniform character throughout be substituted for thepolychrome ribbon 50 and it be desired to feed said uniform ribbonautomatically substantially from one edge to the other thereof duringthe Iongitudinal feeding of said ribbon, tne eccentric strap 78 may bedisconnected from the operating arm 69 by pressin the handle 86 0t 88isengages from the stud 90; and thereafter, by manipulating the handle83, the slotted extension of the strap 77 may be caused to engage withits associate stud 89 on the operatmg arm. The

throw of the larger eccentric is of an extent to provide for feeding theribbon crosswise substantially from one edge to the 1 other thereof.

Of course if desired both the eccentric devices may be put out ofoperation and the guide 52 may be set entirely by hand, as

heretofore.

Where, as in the resent case, the longitudinal ribbon feeding mechanismis connected with and actuated by the. carriage power or spring drum, ithas usually happened heretofore that when the carria e is released fromits escapement devices either by operathig the usual releasekey, or atabulator key or otherwise, and is drawn fully or impelled varyingdistances toward the left, the ribbon will be fed longitudinallycorresponding distances. Darin such feeding of the ribbon the printingevic s are inactive and consequentlv a section of the ribbon.corresponding to the distance which the carriage umps or is drawnfreely, Wlll pass the printing point without being used; that is,without receiving: impressions y from the. types. As the ink in theribbon becomes more and 'more extinct in use. these 3 unused sections orpatches become more apparent in the printed work, some of the charactersbeing much darker than others, with project the vstops 1071 forward bypush rods 101' umlcrlyinglthe base of the machine and (Xtotnltlllftore-:and aft thereof, said push rods each l)(.;H'Hl-; f near the troutof the mafv chine in a detachable bearing member 107 the result that thewn'tin; has an irregular.

The stops 105 are adapted to cooperatewith one or more column stops 110 on a rack bar 111 supported onbrackets 112 detachably secured to the carriage. In orderto'antoluatically release the carriage when any one of the stop bladeslt t operated, a universal bar 112, is arranged transversely behind thestop blades and below the pivots thereof,

bar 93 when raised by the release key, as shown in Fig. 12. acts on theupper fork 95 of an arm 96 which arm is pivoted at J? to the upper endof a rock shaft Q8. The lower-fork 99 of the arm 96 underlies an arn r ltl (Figs. 2, 3, l3 and 1-1), which is pivoted at 101 to the frame of themachine and t-.o '3perates with the lever 15 at the opposite side of theshaft 16 from the pinion 14. When the forward end of the release key 91is depresscdthe nose at the rear end thereof swings the bar 93 up to thepositi n shown in Fig. 12, said bar 93 A leaf spring 120, acting againstthe universal bar 11 tends to maintain the latter in normal position asillustrated in Fig. 1. When one of the linger buttons 108 is pressed in,the corresponding blade 104 is swung on its pivot, projecting theassociate denomination stop 105 into the path of the column stops 110,as shown in ig. 7, and

The releasing arm 121 ispivoted at 122 at the top and rear of the machine frame and extends fromits drum, being formed with an upwardly bent portion 121 which overliesthe fork J5 and is adapted to be operated thereby, (Figs. 1, 2, 7, 12and 13). The left-hand end portion 121' of the releasing arm normallyrestson the top plate and the end thereof underlie-s the rearwardlyinclined or cam end 123 of an extension 124- which is formed integralwith and projects upward from a release ring or annulus 125.

Said annulus issup- The arm 115 of the releasing frame of the ported on an arm 126formed'integrally therewith and extending vertically ownward anddiametrically opposite to the extension 124. Near its lower end the arm126 is provided with forwardly projecting cars 127 which receivea pivotpin 128 sa orted on a block or bragket 129, said racket being bifurcatedto embrace the left- .10 hand side of the base 1 and being detach ablysecured thereto by a screw 130. A leaf spring 131, secured to the block129 by a screw 132, contacts with thesfront face of constantly tomaintain the member camposed of the arm 126, annulus125 and extension121 in the normal position shown in Fig. 1. A lip 126 integral with thearm 126 and extending below the pivot 128 is adapted to contact with theblock 129 to limit the rearward movement of the member under theinfluence of the spr'n 131. From an inspection of Fig. 1, it will heseen that normally the annulus 125 is in a plane behind a planecontaining the rear face of the ratchet wheel 34. As presently tobedescribed the ammlus-carrymg member is adapted to be swung forward bythe operation' of the releasing arni 121 until it partly encircles theratchet wheel 34, as shown in Fig. 7. During its forward movement theouter face of theannulus engages a pin or stud 133 fixed to andprojecting rearward from the pawl below the pivot thereof '(Figs. 1, 2,3, 7 and 11). As clearly shown in Figs. 3 and 11, the stud 133 iscutaway to provide a cam face 133 which face is actcdon by the annulusin its forward swing -to' force the pawl 35 to turn on its pivot againstthe pull'of the spring 37 and disengage the pawl tooth 40 from the teethof the ratchet wheel 34, thereby disconnecting the earria e power fromthe ribbon mechanism. T e awl 35 and stud 133 beiugon the 5 ring rumrevolve. in a circular path, but t e annulus 125 having a corres ondingcircular face will coiinerate with v t c stud 133 at any point inthepath of revolution of said stud.

As clearly shown in Figs. 12 and 13 the bent: portion 121 of thereleasing arm 121 overlies the fork 95 near the root or junction of saidfork with the arm 96. When the release key 91 is operated to release thecarriage from its step-by-step feeding devices,

the fork 95 in its upward movement will contact with the bent portion ofthe arm 121 'and will swing said arm upward on its pivot 122, causm thefree end of said arm to engage with the cam 123, swin ing the annuluscarrying member forwar on its pivot 128 and causing the annulus 125 atsome point on its outer face to act against the cam 133 to disconnectthe pawl 35 from the ratchet whee1.34.

tabulator is provided above the pivot 103 with 31.1 upwardl andforwardly curving extension 115, tie end of said extension havingsuitably secured to it a cam late 115 which is adapted to contact withbracket 134 riveted to the part 121" of the releasing arm. When one ofthe tabulator keys 108 is operated the arm or extension 115' is swungforward, causing the earn 115" to'engage with the lower edge of the,outer end of the bracket 134, lifting the latter and through it swingingthe releasing arm 121 upward on its pivot to act on the cam 123, causingthe ratchet 125 to disengage the pawl from the ratchet wheel 34, aspreviously described in connection with the operation of the release key91.

It will be seen that the release key and the key controlled tabulatin'gmechanism are operative independently of each other to release thecarriage and cut out the ribbon. Further it will be noted that saidrelease key and said tabulating mechanism are operalive to release thecarriage by breakin the train of carriage feeding devices at di fercntpoints, the release key separating the feed rack and feed pinion whilethe tabulating mechanism separates. the engaged dog from theescapemcntwheel.

Various changes may be made without departing from the spirit and scopeof my invention. 1
